Install gopls: go install golang.org/x/tools/gopls@latest

Configure your MCP client: This will be different but similar for each client. For Claude Desktop, add the following to ~/Library/Application\ Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "language-server": {
      "command": "mcp-language-server",
      "args": ["--workspace", "/Users/you/dev/yourproject/", "--lsp", "gopls"],
      "env": {
        "PATH": "/opt/homebrew/bin:/Users/you/go/bin",
        "GOPATH": "/users/you/go",
        "GOCACHE": "/users/you/Library/Caches/go-build",
        "GOMODCACHE": "/Users/you/go/pkg/mod"
      }
    }
  }
}

Note: Not all clients will need these environment variables. For Claude Desktop you will need to update the environment variables above based on your machine and username:

• PATH needs to contain the path to go and to gopls. Get this with echo $(which go):$(which gopls)
• GOPATH, GOCACHE, and GOMODCACHE may be different on your machine. These are the defaults.

Install rust-analyzer: rustup component add rust-analyzer

        "--workspace",
        "/Users/you/dev/yourproject/",
        "--lsp",
        "rust-analyzer"
      ]
    }
  }
}

        "/Users/you/dev/yourproject/",
        "--lsp",
        "pyright-langserver",
        "--",

        "--lsp",
        "typescript-language-server",
        "--",
        "--stdio"
      ]
    }
  }
}

Install clangd: Download prebuilt binaries from the official LLVM releases page or install via your system's package manager (e.g., apt install clangd, brew install clangd).

Configure your MCP client: This will be different but similar for each client. For Claude Desktop, add the following to ~/Library/Application\\ Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "language-server": {
      "command": "mcp-language-server",
      "args": [
        "--workspace",
        "/Users/you/dev/yourproject/",
        "--lsp",
        "/path/to/your/clangd_binary",
        "--",
        "--compile-commands-dir=/path/to/yourproject/build_or_compile_commands_dir"
      ]
    }
  }
}

<p><strong>Note</strong>:</p>
<ul>
  <li>Replace <code>/path/to/your/clangd_binary</code> with the actual path to your clangd executable.</li>
  <li><code>--compile-commands-dir</code> should point to the directory containing your <code>compile_commands.json</code> file (e.g., <code>./build</code>, <code>./cmake-build-debug</code>).</li>
  <li>Ensure <code>compile_commands.json</code> is generated for your project for clangd to work effectively.</li>
</ul>

I have only tested this repo with the servers above but it should be compatible with many more. Note:

• The language server must communicate over stdio.
• Any aruments after -- are sent as arguments to the language server.
• Any env variables are passed on to the language server.
